Introduction

Injection molded products refer to products that are heated, plasticized, and melted during the plastic injection molding process, resulting in molten plastic that is injected into the cavity of a mold. After cooling, the melt is solidified and then demoulded. The injection molding machine then injection molds the product.

In fact, all products molded by injection molding machines are injection molded products. plastic injection molding processes including thermoplastic and now some thermoset injection molded products. plastic injection molding process.

One of the most important properties of thermoplastic products is that the raw material can be injected repeatedly, but some of the physical and chemical properties of the raw material are degraded.Therefore, injection molded products usually do not use raw materials again.

The injection molding process is widely used to produce household items in everyday life from commercial, industrial and consumer products.

Injection molding offers the versatility to produce complex designs of any size. But in life, many people don’t know what finished injection molding products are. This article mainly introduces common injection molding products.

The Definition and Importance of Injection Molding

What is the Definition and Principle of Injection Molding?

Injection Molding

Also called injection moulding, its principle is to add granule or powder raw materials to the hopper of an injection machine. Raw materials are heated, melted, and made to flow. They are injected through the nozzle and screw or piston mold of an injection molding machine. The system enters the mold cavity and is cured and formed within the mold cavity.

What is the Importance of Injection Molding in Modern Manufacturing?

The Advantages of Injection Molding

Short molding cycle, high production efficiency, and easy automation; it can produce plastic parts with complex shapes, precise dimensions, and metal components or non-metal inserts; stable product quality; wide application range.

Industrial products include kitchen utensils (trash cans, bowls, buckets, pans, cutlery, various containers), electrical equipment housings (hair dryers, vacuum cleaners, blenders, etc.), toys, games and cars . Various industrial products, certain cosmetic packaging (bottles, capsules).

Parts for many other products, etc. The injection molding process can produce parts such as electronic casings, agricultural products, toys, and mechanical components.

What are the Commonly Used Materials for Injection Molding?

Commonly used injection molding materials and plastic materials suitable for injection molding include PE, PP, PS and other thermoplastics suitable for hot injection molding.

PE(Polyethylene)

PE is one of the most commonly used polymer materials in daily life. Widely used in the production of plastic bags, plastic films, and milk buckets.

PP(Polypropylene)

Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The mechanical properties of polypropylene are higher than those of polyethylene, but they are still relatively low among plastic materials.

Its tensile strength can only reach 30 MPa or slightly higher. Polypropylene with a high isotactic index has a high tensile strength, but as the isotactic index increases, the impact resistance of the material decreases, but when it decreases to a certain value, the impact resistance remains unchanged.
